Determine whether the following statement regarding the mechanism of the SERCA pump is TRUE (T) or FALSE (F). 1. In the E1 conformation, the two Ca2+-binding sites are exposed on the luminal side of the ER or sarcoplasmic reticulum. 2. ATP binding alone drives a conformation change from E1 to E2.
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
